Hadith 2:74

Narrated Anas:

The Prophet said, "Whoever slaughtered (his sacrifice) before the 'Id
prayer, should slaughter again." A man stood up and said, "This is the
day on which one has desire for meat," and he mentioned something
about his neighbors. It seemed that the Prophet I believed him. Then
the same man added, "I have a young she-goat which is dearer to me
than the meat of two sheep." The Prophet permitted him to slaughter it
as a sacrifice. I do not know whether that permission was valid only
for him or for others as well.
